118 REPORT — 1859. 



and Down coasts along with P. striatus. It was again taken this year, and at once 



distinguished hy Mr. Jeffreys. 

 Pecten Danicus, dead. A single valve in 80 fathoms. In the former list, 1857, with a mark 



as being doubtful. This proves Dr. Dickie to have been correct. 

 Modiola modiolus, living. A small variety, three inches in length, occurs in deep water. 



The same at the Copelands. It is stated that specimens have been found on the West 



coast of Scotland, seven or eight inches long. 



phaseolina, living. With the last in deep water. 



Astarte compressa, dead. A few valves of the smooth variety, found by Mr. Jeffreys in the 



Turbot-bank sand. 

 Telliua pygmsea, dead. Valves united; from the Turbot-bank sand, in Mr. Hyndman's 



cabinet. 

 Solecurtus candidus, dead. In the Turbot-bank sand. 

 Sphaenia Binghami, dead. Not uncommon in pieces of rolled chalk, and among the roots of 



Laminaria digitata by Mr. Grainger. Mr. Jeffreys doubts its having the power of 



burrowing or excavating. See Mr. Jeffreys' " Gleanings " in the ' Annals of Natural 



History ' for Sept. 1859. 

 Mya truncata. A young living specimen was brought up by the dredge from 80 fathoms on 



stony ground ; its usual habitat being low-water mark in mud. 

 Saxicava arctica, living. Not uncommon, moored in cavities or crevices of stones and shells. 



Mr. Jeffreys considers it to be merely a variety of & rugosa, differing in habitat. The 



latter, when enclosed in stone, loses the sharp keel and teeth of S. arctica, and is more 



rugged in appearance. 

 Pholadidea papyracea, living. At a depth of 80 fathoms North of the Maidens, in small pieces 



of soft sandstone. The smaller specimens want the cup-shaped appendage, whether 



the effect of insufficient space or immature growth. 



An examination of these smaller specimens affords means of correcting an error in 



the first list of 1857. The so-called Pholas striata, being identical with these, is 



therefore to be expunged. 

 Cynthia limacina, living. On stones and shells from deep water. 

 Balanus tulipa alba (Hameri of Darwin) is not uncommon, living in the deep water. 

 Balanus ? Of another species, not yet determined, a single dead specimen was found 



in 80 fathoms. 

 Sphaenotrochus Wrightii. A few dead specimens were found in the Turbot-bank sand by 



Mr. Hyndman in 1852, and subsequently by Mr. Waller. Dr. Perceval Wright, having 



seen these specimens in Mr. Hyndman's collections, received permission to hand them 



over to Mr. Gosse, who has described and figured them in the ' Dublin Natural His- 

 tory Review' for April 1859. 

 Sagartia coccinea. A sea anemone appearing to be this species is not unfrequent on stones 



and shells from deep water. 

 Appendicularia flagellum. On the 7th of June, 1859, a bright calm day, this curious and 



interesting animal was seen in great abundance floating through the water at the 



northern entrance of Belfast Bay. It has not hitherto been recorded as Irish ; but 



has been fully described by Professor Huxley in the ' Microscopic Journal,' vol. iv. 

 Sagitta bipunctata. Several specimens were taken in the towing net along with the former. 



Dr. Wyville Thomson had discovered it a short time previously in Strangford Lough. 



Not hitherto recorded as Irish ?. It has been described by Dr. Busk in the ' Micro- 

 scopic Journal,' vol. iv. 

 Ilippolyte spinus. In the deep water off the Maidens : determined by Dr. Kinahan. A 



Northern species, inhabiting the seas of Iceland and Greenland. New to the Irish list. 

 Acanthonotus testudo. Taken with the last. 



A pleistocene bed of stratified gravel was observed on the side of the road 

 between Larne and Glenarm, and was examined by Mr. Jeffreys and Mr. 

 Hyndman. It was found to contain several species of shells, corresponding 

 with those from a bed at the Belfast Water Works, recorded in Portlock's 

 Report on the Geology of Londonderry. 



The following is a List of the species obtained, which will no doubt be 

 augmented on further investigation : — 



Pholas crispata, fragments. Astarte elliptica. Natica clausa (nana Moller). 



Telliua solidula. Mytilus edulis, fragments. Buccinumundulatum(M611er). 



calcarea (Moller). Leda oblonga. Trophon clathratus. 



Mactra subtruncata. Hypothyris psittacea. Mangelia turricula. 



Astarte compressa, var. glo- Turritella polavis (Moller). Pingelii (Moller). 



bosa. Natica Montagui. Balanus tulipa alba.
